SHEET-METAL WHEEL.

Specification of Letters Patent.

Application led. February 25, 1920. Serial No. 361,190.

To all fwwnt 'it may concern:

Be -it known that I, PIERRE L. Lmssn,

' citizen of the French Republic, residing at This wheel is formed in aknown manner by a stamped sheet metal annulus ci conical form. Theannulus is provided with a central opening to facilitate mounting anddemounting of the wheel. The wheel 1s secured by bolts and nuts on adisc of a diameter corresponding to the central opening in wheels, thedisc carried by the ub is thenv panying drawing,

the annulus and carried by the hub or the axletree arm or stub shaft.

When these wheels are emplo ed as rear replaced by the brake drum.Wheels of this t pe having a large central opening, are lighter than thestamped sheet metal wheels generally employed,`which facilitates mount.-ing and demounting of these wheels; further, the vibratory movement ofthese wheels is less than ordinary sheet metal wheels, because they areactually formed of twoA members, the disc and the annulus connected bymeans of bolts.

The invention further relates to arrangements of details which preventsthe loosening of the securing nuts of the annulus to the disc ashereinaterexplained.

In order that'the invention may be clearly understood reference is madeto the accomwherein Figure 1 is ya vertical section of a metallic wheelin accordance w th the present invention, mounted on the rear axle of avehicle;

Figure 2 is a side view of part of the wheel in side elevation.

Fi re 3 shows a developed section of the ann us and disc adj aeent thesecuring bolts.

`The wheel is formed in the ordinary manner by a stamped sheet metaldisc 1 so as to form a light conical structure. To the pe- Patented Jan.17, 1922. y

riphery of the disc 1 is riveted or'otherwise i suitably secured afelloe to receive the ,pneug matic or other tire. The annulus lis prointhe construction where the wheel is mounted `on the rear axle of anautomobile, on a brake drum 4 carried by the end of the transmissionshaft 5. The annulus lis secured on the brake drum 4 by bolts and lnuts6, 7 the bolts are non-rotatably mounted in the drum 4. The innerperiphery ofy lthe annulus l is slightly corrugated, the co1'- rugationsbeing preferably radial (see Figure 3). nulus is made thus acquires acertain amount; of elasticity, which on account of this elasticityprevents accidental loosening of the nuts 7 In the case of front wheelsfor an automobile, the brake drum 4 may be replaced by a disc ofsuitable diameter, secured to the axlef Y tree arm or stub shaft and onwhich isboltedthe metal annulus of the wheel.

A metallic Wheel of this kind, havin a large central opening is ofgreat/rigity v vided with a central opening 3 and is securedy..

The sheet metal of which the anand is lighter than metallic disc wheelsgeni erallyemployed. The vibratory movement of a wheel formed of twointerconnected pieces or members is inferior to that of a disc wheelformed in one piece. Further in the case of rear wheels the utilizationof the brake drum permits. of employing a more simple construction ofhub, as well as an appreciable economy in construction.

Claim- A stamped'sheet metal wheel of the disc type, comprising anauxiliary, axle-supported disc-like member, a central opening formed inthe'web of said wheel, radial corrugations provided adjacent saidopening, adapted to engage the auxiliary disc-like member, andfastenings for resilientl securing together, at the junction thereoi,the web o f said vwheel and its axle-supported disc-like member.

In testimon whereof I a'lix my signature, in presence o two witnesses..
